Languages are incredibly neat. Wikipedia, with its 200+ editions, has rekindled a desire in me to learn more about both the sheer variety of languages in existence and how languages function in general. Therefore, a project of mine will be to become a more useful contributor in multiple languages. (This project is also known as "My excuse to relearn Spanish".) Eventually, I'd also like to pick up a basic knowledge of some relatively unknown language (right now, I'm leanings towards Cornish for various reasons) and contribute in that language as well.

I don't know precisely what will come of this plan, but it's a nice long-term goal to have.
